Title: Centrifugal chemical analyzer of the rotating spectorphotometer type having a digital subtraction circuit
IPC: G06F17/00
Filed: 1973-09-20
Abstract: 1396637 Photo-electric rotary chemical analyzer UNION CARBIDE CORP 20 Sept 1973 [21 Sept 1972] 44206/73 Heading G1A A digital signal processing circuit is provided to subtract the reference value from signal values dependent on the light absorbance of the reaction samples in a multi-cuvette rotary chemical analyzer. The reference value is derived from one cuvette containing e.g. distilled water. As shown, Fig.1, a P.T.F.E. sample disc 1 is mounted in a rotor with corresponding cuvettes 9 which pass through a beam of light directed on to a photo-multiplier detector 13. The detector output is fed to a "linearising" logarithmic amplifier 15 and thence to a peak detector 16, and A/D converter 21. The binary values passed to a subtraction circuit 23, controlled by a timing function generator synchronized with the rotor. The operation of the subtraction circuit is shown in block diagram form in, Fig.2, and starts with the "once around pulse" clearing the shift register 140 and entering an arbitary, binary number (e.g. 240) from the loading circuit to prevent the resultant calculation becoming negative. This number is subtracted from the reference value and the resulting modified value passed thro gate 130 to the register. Gate 130 is now "closed" and gate 120 enabled so that this modified value is stored by recycling to the register everytime it is applied to the subtraction unit for use with data from subsequent cuvettes. The circuit is illustrated in slightly greater detail, Fig.3 (not shown).

Title: Production of cermaic microspheres
IPC: F26B3/34
Filed: 1971-09-29
Abstract: 1407978 Producing ceramic microspheres UNITED KINGDOM ATOMIC ENERGY AUTHORITY 29 Sept 1972 [29 Sept 1971] 45373/71 Heading F4G In the production of nuclear fuels, catalysts, or ceramics, gel microspheres are formed by gelation, are dried without surface pitting or cracking by subjecting them to microwave radiation (e.g. at 2450 MHz), and are sintered to produce ceramic microspheres. The microspheres are placed in an open container which is then located in an oven enclosure to which microwave energy is transmitted via a wave guide from a magnetron. A flow of air is maintained through the oven to prevent condensation. The microwaves may be applied by a helical coil wound around a column of moving material. The microspheres may be formed with a flow of water into monolayers, on the tiers of a stand, or a belt passing through a microwave tunnel. The microspheres may be tumbled while exposed to microwave radiation, in a rotary oven, or fluidized using a gas flow, or otherwise agitated.

Title: Moulding Foamed Articles
IPC: B29C33/10
Filed: 1966-10-11
Abstract: 1,158,171. Foaming; gaskets therefor. CARL FREUDENBERG. 11 Oct., 1966 [12 Oct., 1965], No. 45444/66. Heading B5A. Bodies of foamed polymeric material, e.g. polyurethane, are produced by placing a foamable paste in an open mould body, clamping a closure thereover with a gasket of porous, fibrous material therebetween in order to allow escape of air whilst retaining the desired pressure on foaming the paste, the gasket thereby becoming clogged and removing the foamed body and gasket from the mould. The gasket is usually a fibrous sheet completely covering the opening of the mould body, the porosity thereof and conditions of foaming being such that the pores thereof become clogged quickly during foaming, thereby substantially preventing migration of foam along the sheet between the mould body and closure. The sheet is preferably a needled fleece which remains bonded to the moulded body on removal from the mould, and preferably contains absorbent fibres. A P.V.C. film may be laid loosely in the open mould before introducing the paste, and foaming while allowing the film to move and be forced to contact the contours of part of the mould surface. A smooth surface to the polyurethane may alternatively be obtained if the mould surfaces are of cold vulcanized silicone rubber or have a polymerization catalyst, e.g. an organo-tin compound, available thereon.

Abstract: 1,072,178. Stoning fruit. SUNSWEET GROWERS Inc. Oct. 27, 1965, No. 45489/65. Heading A4C. [Also in Division B8] Apparatus for pitting drupaceous fruit, especially prunes, by means of a reciprocable pitting plunger, includes means for rolling the fruit into a cylindrical form prior to delivering a succession of single fruits to the pitting part of the apparatus, the fruit being shaped between an upwardly inclined supporting surface and overlying rollers. The feeding and shaping apparatus (10) (Figs. 1, 3, 4, 5, 6) comprisers an endless conveyer (25) having spaced transverse rollers (37) carried between driven chains (39), an upwardly inclined support plate (32, 33, 34) disposed beneath and parallel to the bottom run of the conveyer (25), and means, e.g. a conveyer (C), for feeding the fruit to the lower end of the support plate (32). The fruits are carried upwardly along the plate (32, 33) to pass beneath a rotary turret (26) comprising star wheels (56, 57) carrying rollers (58) which co-operate with an arcuate portion of the support plate (33) to shape the fruits therebetween to a cylindrical form. The shaped fruits pass upwardly to be deposited on a bifurcated shelf (38) and picked up by the pitting part (11) of the apparatus. The pitting apparatus includes a rotary turret (27) (Fig. 2) carrying a plurality of buckets (97) (Fig. 11) comprising a pivoted arm (115) with laterally extending fingers (118) which pass through the bifurcated shelf (38) to pick up a fruit. The bucket (97) is then lowered and moved axially toward a pitting die (160) (Fig. 21) and the pitting plunger (120) is simultaneously moved to engage the fruit against the die (160). The plunger (120) is then withdrawn and the fruit is engaged at two diametrically opposite pairs of points by pairs of gripping fingers (131) which centre the fruit relative to the die (160) and the pit relative to the flesh. The plunger (120) is then advanced to press the pit (P) through the die (160), the gripping fingers (131) being partially retracted as soon as the plunger (120) engages the fruit. After pitting, the fruit is withdrawn in the bucket (97) and re-clamped in the gripping fingers (131) to restore its elongate shape and to partially close its open ends. The pitted fruit is finally released and discharged into a shoot (28) after 180 degrees rotation of the rotary turret (27). The whole operation of the moving parts is controlled in timed sequence by various camming surfaces with associated roller followers.

Title: Device for dispensing measured quantities of liquids

Abstract: 948,253. Delivering measured quantities of liquid. WERNER MACHINERY CO. Dec. 10, 1962, No. 46617/62. Heading B8N. An apparatus for delivering measured quantities of liquid, such as milk, comprises a vessel 12 having a milk inlet 18, a vacuum inlet 58, venting orifices 67 covered by a resilient valve member 68, a float 40 mounted on a movable spindle 46 carrying a vacuum valve element 60, and an actuator 70 adapted to lift the valve member 68 when the liquid reaches a predetermined level so as to release the vacuum and thereby allow the liquid to drain from the vessel through an outlet 20. The vacuum inlet is in the form of a nozzle 24 projecting from a boss 66 on a cover 14 for the vessel 12, the venting orifices 67 being drilled through the boss. The float 40 is secured to the spindle 46 which is guided at one end, by means of a cross-piece 50 located in the outlet 20 and, at the other end, by means of a reduced diameter portion 56 moving in the nozzle 24. A closure member 30 for the outlet 20 is mounted on a pivoted lever 22 weighted so as to normally pivot the closure member into the closed position; the lever is adapted to be easily removable from its pivot 40. In operation, when a suction is applied to the nozzle 24, liquid is drawn into the vessel through the inlet 18 via a non-return valve 28 and after a certain level is reached in the vessel, the actuator 70 lifts the resilient valve 68 off the orifice 67 to thereby break the vacuum, the valve 60 simultaneously closing off the vacuum inlet. The weight of the liquid then causes the outlet valve 30 to open, thereby dispersing the liquid into a container, the non-return valve 28 being closed by the pressure of liquid. The orifices may be of the same size as shown, or there may be one small hole for the actuator 70 together with a number of larger round or elongated holes.
